In order to make it easier to download files on my site I’ve edited the code to place a download link under all the files.
Unfortunately doing so has messed up the text on page, removing paragraph returns. So now you wills see all the introduction to lesson text as a block without spacing. It may take me a few days to fix this problem.
However, teachers will find it easier to get to the files they want. So you win some and lose some. I apologize for the overall sloppy looking posts and will get this corrected as quickly as possible.
